I'm aware of the behaviour, I can't speak to its intention (well, the part 
where it symlinks back to the original patch I suspect intended to allow you 
to update the patch in the metadata, but I don't know why we also copy the 
patch to the WORKDIR as well). 

However if I needed to do what you want to do I would do it differently - 
instead of modifying the patches, why not just modify the file(s) in the source 
code directly? I would suggest using sed in a do_configure_prepend() to change 
the values in the source to the desired value from a variable. Depending on 
the complexity you could have the patches change the values to some easily 
replaceable string beforehand.

Cheers,
Paul
